'To @Zt whom t may concern:

B e 1t known that I, JOSEPH M. STELMACH, a citizen of the United States, residing at St. Paul, in the county of Ramsey and` State of Minnesota, have invented certain new and useful Improvements in Rotary Slicers and Graters, of which the following is a specification.

This invention relates to lnew and useful.`

improvements in vegetable"'sl`icers and graters also egg beaters, the primary object of the invention being to' provide a device wherein eggs, cream or the like may be whipped at thel Sametime vegetables, fruit Y or the like are being sliced, grated or otherwise divided.

moved out lof the path of movement'of saidl plates when they are being removed or assembled with the device.

Another object of the invention is t'o'pro vide a device of the above nature whichl will eiioiently accomplishv the vabove functions with a structure whichl is strong, durable and which may be manufactured at a minimum cost.

The invention also consists in the construction, arrangement and cooperation of c elements as will be more fully set forth in the following description.

In the accompanying drawingsforming a part of this application and wherein like numerals areA employed to designate like parts throughout the several views- Figure 1 is a vertical 'section through the invention.

Figure 2 is a top plan of the invention.

Figure 3 is a transverse section taken on the line 3 3 of Figure 1.

Figure 4 is a side elevation of the invention, parts thereof being broken away.

Figure 5 is atop plan of a portion of the device illustrating the slicer plate. y

' transverse section through Figure 6 is a.

y the slicer plate taken on the line 6-6 of Figure 9 are details illustrating the mounting of the anti friction rollers carried by the frame.

Figure 10A is an elevation of a dasher used in conjunction with the invention, and

Figure 11 is a perspective view of a follower device. i

Referring now vmore particularlyA to the drawings wherein for the purpose of illustration is shown the preferred embodiment lofthe invention, the numeral 1 designates a supporting frame which in the present instance consists of a circular platform 2 retained in spaced relation to a table top or the like by supporting legs The platform 2'is provided with an enlarged central opening, and secured concentrically to the platform 2 is a ring like member 4, the opening of which coincides with the opening in the platform. The ring like member is provided with spider legs 5, the inner ends of which merge into a-central bearing plate 6 having a central aperture therein. This ring like plate 4 and central plate 6 are provided with anti friction rollers which project a distance beyond the upper face of the ring like plate and central plate for a purpose which will presently appear.

A post or shaft 8 is journaled in the aperture of the central plate 6 and projects slightly below the same to have secured thereto abeveledr gear 9 which meshes with a similar gear 10 carried by an operating shaft 11. As most clearly seen in Figure 10 the lower end of the post or shaft 8 is provided with a threaded axially extending opening to receive therein the upper threaded end of `a dasher shank 12. The lowerr end of the rshank is equipped with suitable dasher blades 13 which are adapted to rotate within a receptacle 14,. shown in Fig. 4,

' when the dasher is associated with the post shank may extend therethrough.

` 'Ihe operating shaft 11 is journaled in any suitable manner beneath the platform 2 and has keyed thereto a pinion 17 which is Yadapted to project through slots .18in both the platform 2 and the ring like plate 4.

rIhe outer end of the operating shaft extends beyond the frame and is there provided with a pinion 19 which is adapted for mesh with :are provided and are interchangeable.

Figure l, I have illustrated a grater plate or disk resting'upon the anti-friction rollers 7 and which is provided a central aperture whereby the plates may be passed over the post or shaft 8. The only difference between the grater and slicer plates is that the grater plate is provided with the usual. y

grater teeth23 as shown in vFigure 8,' while the slicer plate is provided with the 'usual slots 24 and adjustable knivesA 25. The

grater plate 26, as well as the slicer plate 27 is provided with circumferentially arranged space-d openings y28 whereby the teeth of thepinion 17 may cooperate'therewith for rotating theplates. It will of course 'be obvious that rack teeth'may be provided upon these plates for intermeshing with the pinion 17.. rlhese grater plates are also provided 'with' a pair of spaced, concentric'ally arranged confining walls 29 in the form ofA upstanding fflanges, and as clearly seen in Figures 5 and 7 confine the grater portion of the grater plate.

lt will be noted that the portion of the grat-er plate containing the grater teeth 23 is also provided with openings 30 which are relatively large so that the grated mate-V rial collecting upon the top ofthe plate may be discharged through the openings and will drop through the plate and frame into a Asuitable receptacle arranged beneath the frame.

In order that vegetables and ,fruit may be` held relatively stationary upon the grater vor slicer plates during rotation of the latter, a hopper structure indicated in general by the numeral 3l is.lconnected to the frame or platform 2 so that the hoppery structure may be swung from above the platev being' used in the device to facilitate removal or replacement thereof. This hopper structure, as most clearly seen in Figures l, 2 and 4: consists of a ring like member 32 hinged at one point as at to an upstanding bracket 34 fastened to the platform 2. At a point diametrically opposite the connection of the ring with the bracket retaining` means are provided i for releasably retaining the hopper structure in cooperative relation with` Jthe grater plate.

Rising lfrom the ring 32 and thereto are bridging arms 36, the upper ends thereof being directed toward the center of the device to merge into an apertured bear-v ing yportion 37. The aperture in this ,portion is adapted to encircle 4the upper portion having their marginal edges secured to the placed inthe hopper and upon the grater vegetables or fruit being sliced.

`structure is then swung' over the new fastened i of the postor shaft 8'for steadying the same. n The hopper in the present instance is one consisting of two walls as most clearly seen in Figures l and 2, the two end walls 38 adjacent bridging arms 36, While the outside w'all 39-of the hopper is fastened to the two end walls. The latter have their lower edges notched as at 39 and operating through these notches are the two confining walls of the grater plate, whereby 'either one end or the other, Vdepending upon the directionin which the grater plate rotates,-is adapted to impede'th'e movement ofvegetables or fruitV plate. As shown in Figure 1l, a follower device 40 is illustrated, the arcuateplate 4l thereof being adapted to' be received in the hopper for preventing displacement of the Secured to this' arcuateplate 41 is an u'pstanding handle portion 4t2, the upper end 0f which isA bent outwardly sokthat followerdevice may be hung upon one wall. of the hopper. From the lforegoing description, it will be seen that eggs, Vmilk or the like may be whipped whilevegetables, fruit and the like are being grated and sliced. Upon turning 'movement of thegear 20, rotary movement is transmitted to the operating shaft l1 and to' the beveled gear 9 carried by the post or shaft 3. In the' event that the dasher is associated with the post in the manner heretofore set forth, it will'be apparent that rotary move- As 10o nient will be imparted to the dasher. the pinion 17 meshes'with the' openings 28 in either the grater plate or the slicervplate, rotary movement 'will be imparted 'thereto and when vegetables are placed within the hopper and the platelturned, it will'be ap, 105 .parent that the vvegetables will he sliced in a manner well understood. `When it is desired to change from the slicer plate to the grater plate',- the hopper structure is swung from above the slicer plate, as vshown in F ig. 110

2, whereupon the plate may be readily removed and another replaced.v The hopper plate and is retained in cooperation thereto by the retaining means 35.

The foregoing description and the accompanying drawings have reference to the preferred or approvedY embodiment of my invention. Itis to be understood however that such vchanges 'may be made in the `construc- 120 tion and arrangement of parts, materials,

dimensions, etc.,` as may prove expedientand fall within the scope of the appended claim. v Having thus fully describediny invention what I 'claim' vas new and desire tosecure 125 Letters lPatent `is :-L l

A rotary slicer comprising 'a Asupporting structure, a cutting. disk rotatably 'mounted thereon and provided with a 'pluralityof circumferentially arranged apertures adja-vk 130 i f cent its edge, a driven pinion arranged theref under and having its teeth cooperating and embodying the ring like plate 'adapted to encircle the upstanding flange vof the cutting disk and to be arranged over the apertures of the disk, and means whereby the ring like plate is spaced above the cutting 10 disk. I

n testimony whereof I affix my signaturein presence of two Witnesses.
